Description
This is a classic. Everyone has played with a staircase troll at one point or another and felt the fascination on the body. Just letting the spiral run from hand to hand is enough.
But it didn't get its name for nothing. Stair trolls must go up stairs. Place the stair troll on the top step, lift off the top and tilt it down towards the next step. The rest goes by itself. Shade the path and enjoy the view.
This is a toy that fascinates all ages. In addition to being played with, the stair troll can be used in scientific demonstrations. Imagine holding the spiral at one end so that the whole thing is stretched out and hanging in the air. What happens when you drop on top? Does it fall flat on the ground? Is it pulled together first? The answer will surprise you, but you will only get that by trying it yourself.
The stair roll is 5 cm and made of metal.
